Although acreage is relatively small (about 50,000 acres), sunflower seed is an important crop because California growers produce the seed for planting stock, destined to be planted in many areas around the world for oilseed and confectionary snack food markets.

The impact of cover crops can be variable, depending on plant variety and management practices. Choosing the right cover crop is important and deciding what to plant will depend on your on-farm goals.
Why cover crop?
Cover crops add organic matter to soil, which increases microbial activity, and leads to good soil aggregation and improved soil structure.

About half the soil volume is composed of particles, the other half is soil pores. At field capacity, these pores are roughly filled to equal parts with water and air. Pores are the spaces where roots grow, microbes live, and water and nutrients move through the soil. For this reason, compaction can lead to poor water infiltration,......]]>Mon, 11 Jun 2018 12:00:00 PSThttp://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=27421&utm_source=RSS&utm_medium=RSS&utm_campaign=RSS%2BFeed

The trial is one of several located across the state. The work is funded by UC ANR and is trying to determine if canola......]]>Mon, 07 Apr 2014 12:00:49 PSThttp://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=13495&utm_source=RSS&utm_medium=RSS&utm_campaign=RSS%2BFeed
melundy@ucdavis.edu(Mark Lundy)http://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=13495 What a difference some rain makesWheat is a tough little plant. This is a field that was planted in early November to enough moisture to germinate. After about the 3 leaf stage it got thirsty and spent several weeks withering. By mid-January I was wondering if there would be a crop to harvest (note the plants in the furrows are doing better than those in beds due to the soil moisture difference):
Although we still need more rain (and we're getting some as I write this!), here's what the rains in early February did for the......]]>Fri, 28 Feb 2014 14:43:00 PSThttp://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=12994&utm_source=RSS&utm_medium=RSS&utm_campaign=RSS%2BFeed

melundy@ucdavis.edu(Mark Lundy)http://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=12652 Portrait of a Dry YearEvidence of the drought conditions are all around us. A few that I've noticed just today: orchards being irrigated in January; a rainfed wheat crop planted in October that still hasn't germinated; another wheat crop that's been at the 2-leaf stage for almost 2 weeks and is starting to show signs of severe moisture stress. It's hard to miss the biological consequences of California's driest year on record at the field level. I was curious to see a quantification at the regional level. Here are a......]]>Tue, 07 Jan 2014 10:19:43 PSThttp://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=12513&utm_source=RSS&utm_medium=RSS&utm_campaign=RSS%2BFeed
